2 Claims. (Cl. 150-34) This invention relates to bags and moreparticularly to formula bags adapted to receive a plurality of formulabottles and to maintain them at predetermined temperatures.

In storing infant formula containers such as baby nursing bottles to becarried from place to place as in traveling, such bottles are oftenplaced in bags especially designed for that purpose. Such bags have beenprovided with thermal insulation thereby permitting the bottles to beplaced in the bag in heated condition for example so that theyare readyfor use upon removal from the bag. However, it is often required thatsuch bottles be maintained at different temperatures. Thus, for example,although it may be desired to maintain one bottle in heated conditionready for use, the same trip may require that another bottlebemaintained in cold condition so as to prevent spoilage.

It is, therefore, an object of this invention to provide a formula bagsuitable for carrying formula containers or bottles from place to placeand for maintaining each of said bottles at a predetermined temperature.

Another object of this invention is to provide a formula bag whereinbottles may be maintained separate and apart from each other and in sucha condition as to prevent physical contact therebetween which mightresult in the breakage of such containers.

A further object of this invention is to provide a formular bag with aplurality of independent chambers each of which is adaptedto receive anursing bottle or similar container and to maintain each such containeror bottle and its contents at a predetermined temperature wherein forexample one such container is maintained in warm condition whiletheother is maintained in a lower temperature.

It is also an object of this invention to provide a formula bag of thecharacter indicated which is adapted to contain a plurality of formulabottles or similar containers at such temperatures as may be requiredand wherein means are provided for the insertion or removal FatentedSept. 6, 1955 thermal insulation is provided for each of the endchambers which are spaced from each other so that in addition tomaintaining each of the bottles in thermally insulated condition thetransfer of heat from one compartment to the other due to possibleinfiieciency of the insulting material which may be employed iseffectively bottles positioned therein, in broken lines,

Figure 5 is an end elevational view of the bag, and

Figure 6 is a cross-section of Fig. 4 taken along line 6-6 thereof.

1 As shown in Figs. 1, 2, 4 and 5 the formula bag is comprised of asubstantially rectangular container which is designated generally by thenumeral 10 defined by of each of such bottles independently of oneanother v and without affecting the thermal condition of any otherbottle within said bag.

A still further object of this invention is to provide a formula bag ofthe character indicated which is simple, efficient and may beeconomically constructed and which is provided with bottle receivingchambers as well as a space or compartment for the reception of otherarticles all of which may be readily carried from place to place withoutbreakage.

In order to accomplish these and other purposes, I have provided aformula bag of substantially rectangular configuration havingindependent insulated chambers positioned adjacent the end portionsthereof as well as a main compartment extending the entire width of thebag. Provision is also made for access to each of these chambers or thecompartment through openings which are provided with separable closuremeans positioned along the top and end edges of the bag. Independentside walls 11 and 12, bottom wall 13, top wall 14 and end 'walls 15 and16. The bag is advantageously formed of a film or sheet of flexibleplastic material. It will be understood however that other similarsuitable materials may be used for this purpose. The bag is adapted tobe carried by means of a carrying strap 34 which may be of conventionaltype and which is adapted to be adjusted to the desired length by meansof adjustment loops -17.

As may be more clearly seen from Figs. 3, 4 and 6 the interior of thebag is provided with chambers 18 and 19 adjacent the end walls thereof.Each of the chambers is defined by an inner and outer wall of flexiblesheet material between which a layer of heat insulating material isinterposed. It has been found advantageous to employ glass wool for thispurpose although it will be understood that other similar suitablethermal insulating material may be employed. Thus, chamber 18 is definedby outer wall or cover- 20 and inner wall or lining 22 between which alayer of flexible heat insulation 24 is provided. Similarly, chamber 19is defined by outer wall or cover 23 and inner wall or lining 21 betweenwhich a layer of flexible heat insulation 25 is provided. The end walls15 and 16 are provided with longitudinally extending slits or openings26 and 27 respectively to which complementary separable fasteningelements such as zippers 35 and 36 are secured. Chambers 18 and 19 areprovided with similar longitudinally extending openings the edges of thematerial of said chambers being secured at the sides of slits 26 and 27as by stitching 37, whereby independent access into each of saidchambers is provided through the longitudinal slits or openings in theend walls. It will thus be seen that each of said chambers defines athermally insulated compartment which may be opened or closed from theexterior of the bag to permit the insertion or removal of a nursingbottle or similar container. It will further be noted that in view ofthe remote position of the chambers from each other at the ends of thebag, a substantial physical separation is provided between the chambersthemselves thereby additionally preventing any heat transfer from thecontents of one chamber to the contents of the other.

The interior of the bag is also provided with an inner lining membersubstantially co-extensive therewith which comprises a compartmentdefined by walls 28 and 29, between which a partition wall 31 isinterposed to form sub-compartments 32. It will be noted that the liningmember extends diagonally across the bag so that it is substantiallycoextensive therewith. Access to the liner is provided by means of aslit 33 formed in the top wall 14 of the bag which is similarly closed.

by means of a separable fastening device such as a zipper 39.

The compartment and the subdivisions thereof formed by the lining towhich access is had at the top wall of the bag is adapted to receiveadditional formula containers or such articles as it may be desired totransport or carry therein. By reason of the diagonal position of linercompartment 30, the complete interior spaceof the bag is available foruse when. the end chambers 18 and 19 are empty. It will also be apparentthat when either or both of the chambers are in use the space availablein the liner for the storage of other articles will only be reduced by aminimum amount.

As may be seen by Fig. 4, chambers 18 and 19 are adapted to receiveformula containers such as nursing bottles 38 and are so located thatsuch bottles are spaced from each other at the most remote pointspermitted by the size and configuration of the bag. The chambers areadapted to receive bottles which are either at high or low temperaturesand one chamber may carry a bottle at high temperature while the otheris employed for maintaining a bottle and its contents in cold condition.The bottles are insulated from the external atmosphere and from. eachother. The thermal insulation .serves the additional function of apadding to prevent break age of the fragile containers. The provision ofindependent closure elements at each end of the bag permits. eitherbottle to be removed or inserted at will without in any manner affectingor disturbing the other bottle or its thermal condition. This feature isvery important since such bottles. are often carried about for anextended period of time and any opening of a chamher would naturallyimpair the effectiveness of its thermally insulated condition. Asheretofore pointed out, the bag is readily available for thetransportation or storage of other articles to substantially the fullextent of its interior volume when the chambers are not beingotherwiseutilized and the storage capacity of the bag is only reduced by theminimum amount when .either or both of the chambers are in use. Itshould also be noted that by providing access to the main or liningcompartment by means of an indepedent opening at the top of the bag,articles may be inserted therein or removed therefrom without affectingthe thermally insulated condition of the contents of the chambers.

While I have herein disclosed one embodiment of my invention, it will beunderstoodthat the same may: be embodied in other forms withoutdeparting therefrom.

I claim:
